What is an AI model?

An AI model is a computer program trained on large amounts of data to recognize patterns, make predictions, or generate content without being explicitly programmed for every outcome. Well-known examples include large language models (LLMs) such as GPT and Gemini.

How do AI models work?

AI models learn patterns and relationships from data during training. Once trained, a model can apply what it has learned to new information to generate text, make a prediction, classify information, or recommend an action. Models can also be fine-tuned or further trained to improve accuracy or for specific tasks and use cases.

Why are AI models important?

AI models provide the underlying intelligence behind many AI applications and AI agents. The model an organization chooses can affect what an AI system can do, how well it performs, and what risks need to be managed, including accurate or fabricated outputs known as hallucinations.

Benefits and use cases

AI models power everything from virtual assistants and content generation to demand forecasting, anomaly detection, personalized recommendations, and decision support. They are increasingly used across industries including healthcare, finance, retail, and manufacturing.
